Well, honestly, I figured that since I was already using 2 Noctua heatsinks, I might as well load up with Noctua fans. It wasn't a necessary measure by any means. The big fan is actually pretty good. I have the one on the front running at 7V and it's whisper quiet.

Ok,

Did you use one of the 7V connector bundled with the Noctuas to reduce voltage on the CM fan?
Because it's what I'm planning to try when my ATCS840+parts comes-in.

I ordered a Noctua P12 for my S1283 DK HSF, and I will use the adaptor provided by Noctua for slow down one of the 230mm on top of the case (the front one) to reduce short circuit air flow. I also added a Scythe Kama Bay+ for the front of the case.

Good thing I looked at your topic, it helped me out

Yep, I wasn't planning on using the low-voltage adapters for my P12s themselves, so I stuck them on the stock CM fans. The stock 120mm fan (using it as a bottom intake) spins at around [email protected], while the 230mm (front intake) spins at around [email protected], and I can't hear anything. I mean, with 8 fans the machine's not quite silent, but it's significantly quieter than the ambient noise level in my room (tower fan for circulation, panaflos in my primary rig, noisy housemates ). I need to turn everything else off if I want to listen to the fans, but even then they just sound like woooooooooosh
